JOURNAL LUBRICATOB Filed Sept. l0, 1936 2 Sheets-Sheet 2 Patented Sept. 19, 1939 UNITED STATES PATENT OFFICE 2 Claims.

The invention relates to lubricators for journal boxes and has as an object the provision of a lubricator which may be placed while the journal is assembled with the journal box and in which means are provided rigid with the bottom of the journal box to hold the lubricator in position.

It is a further object of the invention to provide means rigid with the journal box with which means carried by the lubricator may be engaged in sliding relation whereby the lubricator may be slipped into place guided by said means.

Further objects of the invention will appear from the following description when read in connection with the accompanying drawings showing illustrative embodiments of the invention and in which Figure 1 is a vertical section of a journal box showing the lubricator partly in section and partly in side elevation;

Figure 2 is a detail transverse section on line 2-2 of Figure 1;

Figure 3 is a detail section similar to Figure 1, showing a different form of the invention;

Figure 4 is a view similar to Figure 1 showing a still further form of the invention, and

Figure 5 is a transverse section on broken line 5-5 of Figure 4. l

As shown in Figure 1, the journal box is indicated at I and a journal at II. The device is designed to be insertable through the usual door I2 of the journal box. To hold the lubricator in place and to guide the same as it is slipped to position, there are shown Z-shaped members I3-I 4, shown as bolted to the bottom of the journal box but which may obviously be cast integral with the journal box.

In this form of the device the lubricator comprises separate absorbent pad means comprising felt members I crescent shaped in elevation and each formed with a leg of felt I6 to project to a position adjacent the bottom of the journal box to act in the nature of a wick, To hold the elements I5 in contact with the journal there are shown coiled springs I6 acting in compression, each of said springs being shown as secured at its lower end to a block I8, preferably of metal, as steel. The blocks I8 are of a size to enter the way formed by the Z-shaped members I3-I4.'

The pad members I5 are shown as provided on each edge with bowed springs 20 desirably stapled to the felt, which bowed springs are initially of less radius of curvature than that of the journal face, so as to cause the pad members to press against the journal surface. The pad members each assembled with its spring I1 and block I8 may be slipped one at a time into place and after assembly in the journal box a Cotter pin or the like, 2l, may be passed through perforations in the ends of the Z-shaped members I3--I4 to prevent escape of the blocks.

(Cl. 30S-88)' In the form of the invention of Figure 3, the means rigid with the journal box is shown in the form of hooks 22, which may be secured in perforations in the bottom of the box, as by means of screw threaded nuts 23. In this form of the invention the springs one by one may be slipped into place while compressed, the rearmost one being placed rst, and a turn of each spring may be engaged with the respective hooks. The turns of the springs which fall below vthe hooks will provide resilient pressure upward against the hooks to prevent separation therefrom.

In the form of the invention of Figure 4, a pair of short Z-shaped members I 3-I4 are shown adjacent to the back end of the box and one spring I1 carries a block I8 engaging the Z- members. In this form of the invention the pad I5' is preferably in one piece and for exibility to enable ready insertion the pad member is shown as relatively thin as compared with the pads I5 of Figure 1. Other springs 24 are shown bearing against the pad I5 and freely engaging the bottom wall of the journal box with wick legs 25 extending downwardly within the springs toa point adjacent the bottom of the box. The forward end of the pad I5 is shown as pressed against the journal by a pair of springs 2li-21 which may be engaged at their lower end upon hooks 28-29, the springs 26-21 flaring and pressing against the pad upon different radii of the journal. By means of the springs 26-21 twisting of the pad I5' will be prevented.

Minor changes mayv be made in the physical embodiment of the invention without departing from lthe spirit thereof within the scope 0f the appended claims.

I claim:

1. `A journal bearing lubricator comprising, in combination: absorptive pad means to supply lubricant to a journal; a plurality of coiled springs acting in compression between said pad means and the wall of the journal box; and a plurality of hooks rigidly carried by said Wall each engaging a turn of one of said springs to preserve the location thereof in the box.

2. A journal bearing lubricator comprising in combination: absorptive pad means to supply lubricant to a journal; a plurality of coiled springs acting in compression between said pad means and the wall of the journal box; and a plurality of hooks rigidly carried by said wall each engaging a turn of one of said springs to preserve the location thereof in the box; at least two of said springs projecting from said pad means upon downwardly daring radii of the journal to prevent twisting of the pad means.
